To all whom t may concern: v

Be it known that I, WILLIAM G. LAnsiiN, a citizen of the United States,and a resident of Steger, in the county of Cook and State of Illinois,have. invented certain new and useful Improvements' in a Skate;` and Ido hereby declare that the following is a full, clear, and exactdescription of the samerreference being had to the accompanying drawingsand to the numerals of reference marked thereon, which form a part ofthis specification.

It isI an object of thisinvention to prepare a skate which may besecurely fastened onto a shoe even when the sole of the shoe is verythin. i

It is afurther object of this invention to providea fastening means forthe toe of the skate which may be readily changed to fit shoes ofdifferent size and shape.`

It is vafurther object of this invention to provide means for adjustingthe length of the skate in a step by step way an-d to arrange theabove-mentioned fastening means so that it shall cor-operate with theadjusting means. y

It is a further object of this invention to providey a lever fortightening the skate upon the shoe which `shall act by drawing the twoend portions of the skate toward one another.

It isa further object of this invention to provide `a brace for theforward wheels of the skate in the case vof a roller skate, or

the forwardportion of the runner in the f case of `an ice skate, and tofasten this brace to the upper par-t of the skate without interferingwith the adjusting o-r fastening means. mentioned above.

Other and further important objects of i this invention will be apparentfrom the disclosures in the accompanying drawings j and the followingspecification. f

`The invention (in a preferred form) is illustrated in the drawings andhereinafter more fully described. y

Figure 4 is a section upon the line 4 4 of Figure 2. j j

Figure 5 is a bottom plan view of a portion ofthe skate.

Figure 6 is a section upon the line 6-G of Figure 5.

As shown on the drawings:` j

The top or platform of the skate is made up of a forward plate 10 and arear plate 11. In the front part of the skate the forward plate 10 is ontop, but in the rear part of the skate the rear plate 11 is on top. Thechange is made as indicated at 12 by the front plate 10 being offsetenough to permit the rear plate 11 to pass through a slot 13 in thefront portion.

The forward plate10 of theskate is attached to the supports 17 in anyusual or convenient manner, as indicated at 14.y

Thesev supports 17 go tothe front wheels in the` case of a roller skateor to the front part of the runner in the case of an ice skate.Theforward portion of the ruimer or the front wheels are furthersupported by meansof a brace 15 which extends upward and rearwardly andterminates in a horizontal portion'16 which contacts with a` flat partof the front plate 10 just to the rear of the plug 13. i i i A bolt 18goes through both plates 10 and 11 to secure the brace 15 in place. Anut 19 is threaded onto the under end of the bolt 18 and a squaredportion 2O is provided just under the `head of the bolt `to afford ashoulder contacting with the upper face of the plate 10. i The sides ofthe squared portion `2O bear against the edges of a slot 21 whichextends from the forward end of the plate 11 to a point near where thisplate widens out to make the support for the heel of the shoe. The`edges of this slot guide the plate 11 in its tele-` scopic movementover and through the plate 10. j

.Further guidance is afforded by a bolt 23 Vwhich is positioned near therear end of the slot 21. The position of the bolt 23 is fixed by meansof abearing piece or washer `24 `which has a pair of ears 25, the outeri ends of which turn down as shown at 26 in Figure 6. i The turneddownends of the ears 25 engage in a pair of holes belonging totherows ofholes 27 provided in the plate-11. These rows are parallel to and oneach side of theslot 21 so that the position of the bolt 23 may bevaried along the slot 21 by placing the ears 25 so that theirdown-turned ends enter the pair of holes 27 which is at the selectedpoint. Then the ends 26 have been placed in theholes 27 N Y, 1,535,422UNITED `STATES PATENT oFFicr-i.j

the bolt 23 is held stationary relative to the part ll.

The portion of the shank of the bolt 23 immediately under the washer 24serves as a guide for the plate ll by contacting with the edges of theslot 21. The portion of the bolt 23 immediately below this serves as aguide for the motion of the plate l() by projecting through a slot 2S inthe plate l0. The slot 28 does not extend as far forward as the bolt 1S,but the threaded part of this bolt passes through a round hole in theplate l0 immediately under the squared portion 20, as may be seen inFigure 3. Thus the bolt 18 moves only with the plate l() and the bolt 23moves only with the plate ll. Pivotally mounted upon the bolt 23immediately below the plate l() is a lever 30, and immediately below thelever the bolt is provided with a shoulder so that a nut 81 screwed uponthe end of the bolt will not clamp the lever 30, part l() and part lltogether and thus introduce friction. At the rear end of the slot 28some of the material of the part is bent downward to form a lug 32. Therear end of the lever is formed into a cam 33 to cooperate with thislug. The lever at its rear end is also supplied with 'a shoulder 34 tocontact with one edge of the lug 32 and act as a stop. The forward endof the lever is provide-d with a downwardly projecting finger piece 34aby which the lever 'is manipulated.

The forward end of the part 10 is provided with a cap or receptacle l()to rece-ive the toe of the shoe. This receptacle may be of whatevershape is necessary to iit the paryticular style of shoe worn by the userof the skate. ln order that this cap may be easily changed toaccommodate different shoes,` it is detachably secured to the part l0.The preferred form of detachable fastening` is illustrated but manyother forms are available. As illustrated, the fastening consists oftongues 41 and l2 integral with the cap and projecting down throughslots in the plate l0. The ends of these tongues are bent against theunder side of the plate l0 to prevent the removal of the cap 40. Then itis desired to remove the cap, it is easy to straighten the tongues. Thereceptacle may be made of any suitable material. If the material ishard, for example if it is sheet metal, it is preferably lined with somesoft material such as felt, as is shown at 43. Preferably provision ismade for ventilation, as for example by means of holes 44 arranged inany desired pattern in the sheet metal cap 40.

In the operation of the device the nut 3l. is iirst loosened until thebolt 23 can be lifted far enough for the ends 26 of the ears 25 to beremoved from the holes 27. The bolt 23 Wit/ll th@ nfaslier 2l is thenmoved lengthwise of the plate 1l until the ears 25 are opposite theselected pair of holes 27. The nut 3l is then again tightened and bringsthe ends 26 of these ears into said holes.

The lever 5l() is then placed at right angles to the positionillustrated in Figure 5, with the result that the cam 33 presents itsnarrowest part to the lug 32. The shoe is then placed vou the skate.This is most conveniently done when the user is wearing the shoe. Heputs his foot into the skate just as he would ordinarily into a shoe.The toe of the shoe enters the housing 40 and the heel of the shoepresses against the heel plate 50 and forces the part ll backward untilthe edge of the cam ib is brought lirmly against the lug The pair ofholes 27 is so selected that this will occur when the shoe has becomelirmly seated against the tlat top of the skate. Preferably there shouldbe a very slight lost motion between the cap 40, the plate 50 and theshoe. When the shoe is thus in position the leve-r 30 is turned into thepositionillustrated in Figure 5, with the result that the cam 33 forcesthe lug` 32 backward. This moves the part l() backward and so lessensthe distance between the cap and the heel plate 50, with the result thatthe shoe is firmly clamped between the two. Thus the clamping upon thetoe of the shoe is effected by the whole bearing surface of the housing40 and does not depend upon clamps pressing against the edge of thesole.

Vertical motion of the parts relative to the shoe is prevented by meansof a strap 5l. It is, however, understood that other fastening means forthe heel may be used instead of this strap.

then the skate is to be removed, the lever 3() is turned through a rightangle, the strap 5l released, and the shoe lifted out. ln order toremove the skate it is not necessary to loosen the nut 31. It need beloosened only when the length of the skate .is to be altered to fit adifferent shoe. It is not necessary to loosen the nut 19 even for suchadjustment of length.

l am aware that numerous details of construction may be varied through awiderange without departing from the principles of this invention, and Itherefore do not purpose limiting the patent granted otherwise than isnecessitated by the prior art.

I claim as my invention:

l. ln a skate, a toe plate, a heel plate telescopically mounted on thetoe plate, said heel plate having a row of holes, a pivot, a mountingfor said pivot, said mounting including a. part adapted to project intoone of said holes, means for securing said mounting in place with saidpart projecting into the selected one of said holes, a lever on saidpivot. and means integral with one oll said plates co-operating withsaid lever to limit the telescopic motion of said plates.

2. In a skate, a heel plate, a toe plate telescopically adjustable withrespectto the heel plate., means for guiding and maintaining said platesin telescopic relation comprising an adjustable iulcrum membel` uponsaid heel plate extending through said toe pla-te, and a cam leverpivoted upon said member, said toe plate having an abutment 'forengagement by said lever.

3. In a skate, a heel plate, a toe plate telescopically adjustable Withrespect to the heel plate, a fulcrum bolt adjustable longi-` tudinallywith respect to the heel plate, and a cam lever mounted upon saidfnlcrnm plate adapted for engaging and shifting said toe plate andlocking the same in adjusted position.

4. In a. skate, a toe plate, a heel plate, said plates beingltelescopically supported and relatively7 adjustable, a depending fulcrumelement adjustable longitudinally with respect to one of said` plates,and a cam lever-pivoted upon said fulcrum element, and adapted forengaging and shifting,l the other plate and locking the same withrespect to j 'the lst plate.

In testimony whereof I have hereunto subscribed my name in the presenceof two subscribing Witnesses.
